<b>概要</b><br><blockquote>



Returns the length of the specified named regular expression group 
after a call to <a href="nextregularexpressionmatch.html">NextRegularExpressionMatch()</a>. 

 

</blockquote><p><b>参数</b></p><blockquote>
<style type="text/css">
table.parameters { border-spacing: 0px; border-style: none; border-collapse: collapse; }
table.parameters td { border-width: 1px; padding: 6px; border-style: solid; border-color: gray; vertical-align: top; font-family:Arial; font-size:10pt; }
</style>
<table width="90%" class="parameters">
<tr><td width="10%"><i>#RegularExpression</i></td>
<td width="90%"> 
 
The regular expression to use. <a href="examineregularexpression.html">ExamineRegularExpression()</a> and 
<a href="nextregularexpressionmatch.html">NextRegularExpressionMatch()</a> must have been called on this regular expression. 

 

</td></tr>
<tr><td><i>GroupName$</i></td>
<td> 
 
The name of the group to extract. The group name is case sensitive.

</table>
</blockquote><p><b>返回值</b></p><blockquote>



Returns the character position of the group. 

 

</blockquote><p><b>Remarks</b></p><blockquote>



Groups in a regular expression are defined by surrounding a sub-expression 
with braces "(" and ")". Groups can either accessed by index using functions 
like <a href="regularexpressiongrouplength.html">RegularExpressionGroupLength()</a> or they can be assigned a name using the 
"(?&lt;name&gt;)" syntax as shown in the example for the <a href="regularexpressionnamedgroup.html">RegularExpressionNamedGroup()</a> 
function.
